I have, last night, I haven't put the bucking back in to see the results yet, but I didn't know if a dirty hop up bucking would result in no performance from the hop up. the guy I bought it from was spraying silicon oil in the mags to get them to work off someone elses advise, and I think that may be the problelm.

The hop up and bucking, exposed to oil and dirt can very well make the hop up ineffective. Make sure the hop up and bucking are not exposed to any oils, especially from the ones from the mags that the guy sprayed silicone oil into, meaning it may be a good idea to clean the mags.

In regards to drop off and ineffective hopup....
If you try and seperate the barrel from the hopup unit, even with the hopup off (up),you can pop the hopup rubber nub out of its seat as you pull the barrel apart from the hopup unit. This will make you lose all hopup and you will not see a change in the bucking when you try and turn the hop up or down. To fix this, you must go against the manual recommendation and take the hopup unit completely apart. Correct reassembly as shown in the pictures solved this for me. I will have to do this again when i install my new barrel and bucking (if i ever do that).

what about the slight lubrication that comes even on KSC bbs? is this bad for the hopup?

The KSC bb's are made by KWA and the KWA platform is designed around the ammo they make, so the polish surface/dry lubrication? around KSC bb's are not bad for the hop up. I would recommend to continue maintaining/cleaning your barrel/hop up, perhaps even after every game.

Loved the write-up, but being a bit of a newb I would LOVE it even more with pictures or video. Heck, I think an official "how-to clean and adjust your hop-up" video from KWA for the M4 line would be a REALLY relevant video.

Hello, i have a question regarding how to clean the inner barrel and that stuff... I just read the dos and donts above and well i bought an ISC lubricant oil spray but now im not sure if i should use it for my pistols. Is it recommended for ALL guns to use just water or is this fine too: http://www.evike.com...oducts_id=25170

There is no place for "silicone" sprays in AEG's or GBB. And NEVER use spray silicone to clean your barrels especially with the inner barrel still attached to the bucking and hop up unit. Just run a patch soaked with dish soap and water solution to clean. Then run a patch with just water to rinse. Finally a couple of dry patches and you are good to go. I sometimes use some rubbing alcohol to clean my barrel but you have to separate the barrel from the bucking and hop up.

I have disposable wipes made by Zeiss used to clean eye glasses, great at removing oily finger prints and such. These wipes use a small amount of alcohol to help remove grease and dry fast.
My question is, would these work on the hop up bucking to clean in the field or would they damage the soft rubber?
